The key must be defined in a keyring.
Front door vrf.
The ivrf of these tunnels can be different and.
The routing instance that is used if no specific vrf is defined.
This step is only required when configuring a front door vrf fvrf.
Under the geographic separation scenario eompls would normally be used to link the two ip networks.
Front door vrf or outside vrf the vrf that contain the encrypted traffic.
Create front door vrf named fvrf on r1 and r4.
When you are using a front door vrf you can t define the key using the old crypto isakmp key command.
Configuring physical interface on r1 and r4 to be vrf aware.
Figure 1 0 shows a typical scenario below this scenario is common amongst service providers and geographic separation is normally sold as part of the solution.
There are other benefits of this design and it s quite commonly used in the sp enterprise world.
The crypto isakmp key command doesn t support vrfs.
One or more ipsec tunnels can terminate on a single interface.
Note front door vrf fvrf is only supported as of cisco ios release 12 2 33 sxh and later.
By using front door vrf we are isolating transport network usually internet facing and this allows us to configure default route that won t interfere with routing in our global table.
If you don t use a keyring you won t be able to apply the key to the isakmp profile so the ipsec configuration won t have access to a.
As you can see we did not move the tunnel11 interface from the global routing table to the routing table for vrf pipe.
Crypto map based with ivrf cust1 vrf and fvrf internet vrf.
Sets the destination address of a tunnel.
Router ospf 100 vrf pipe router id 13 13 13 13 4.
Optional associates a vpn routing and forwarding instance vrf with a specific tunnel destination interface or subinterface.
All we did is stitch them together.
The concept is called fvrf ipsec or in english front door vrf ipsec.
Vrf name name assigned to the vrf.
Modify the tunnel interface to stitch the tunnel to the front door vrf.
Router config if tunnel destination ip address.
